The invention relates to improvements in windows, as described in the present specification and illustrated in th accompanying drawings that form a part of the same.

The invention consists essentially of th novel features in construction as pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of acceptable forms of the invention.

The objects of the invention are to devise a window which may be automatically opened or closed; to contrive a window and operating mechanism therefor which will permit the same to be opened or closed by mechanical or automatic means; to eliminate the necessity of manually opening or closing a window by providing mechanical means electrically controlled; to furnish a window in which a screen replaces the pane of the Window when the latter is moved to an open position; and generally to provide a window which may be easily opened or closed without manual effort and which will be dependable and efficient for its purpose.

Figure 9 is an enlarged fragmentary sectional view as taken on the line 9-9 in Figure 4 and in which the window sill has been removed therefrom.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the invention, as illustrated in Figures 1 to 9 inclusive, consists of a mechanical device adapted to be electrically operated for opening and closing a window and/or filling the opening in the window with a screen when the pane is in an open position.

The window, as indicated by the numeral l5, consists of a window frame I6 suitably mounted within an opening in the wall ll. A pair of outer channels l8 and 19 are fixedly secured to the sides of the frame 16 and adapted to movably support the window pan 20. A pair of inner channels 2i and 22 are fixedly secured to the sides of the frame It and are spaced inward a suitable distance from the outer channels l8 and I9. These inner channels 2| and 22 are adapted to movably support a screen frame 23.

The window pane is preferably of the thermo-sash type, which is a twin seal glass which consists of an inner and outer layer having an air space sealed in therebetween. The window pane 20, as hereinbefore described, is of suflicient thickness and strength to eliminate the necessity of providing a conventional type sash.

The screen frame 23 has a suitable wire mesh 24 secured thereto, and the same is adapted to be raised or lowered in the opposite direction to that in which the window pane 20 is moved.

A horizontal channel 25 is fitted over the lower edge of the window pane and provides a means of mounting an adjusting bracket 26 which is fixedly secured thereto. This adjusting bracket 26 has an internally threaded portion extending vertically therethrough, and is adapted to be engaged by a threaded shaft 21. The upper end of the threaded shaft 21 is rotatably supported in. the sill 28 of the window and extends downward. therefrom towards the bottom of the frame I 6; where it is rotatably supported in a bracket 29.. An adjusting bracket 30 is fixedly secured to the lower portion of the screen frame 23 and is: internally threaded in a similar manner to that of the adjusting bracket 26. The threaded shaft; 3! is rotatably supported at the upper end thereof by the sill 28 and engages the threaded portion of the adjusting bracket 30. The lower end of the threaded shaft 3| is rotatably supported by the bracket 29. Each of the threaded shafts 2? and 3| rotates on thrust bearings 34 and 35 which are mounted on the bracket 29. In this respect it will be seen that the threaded shafts 21 and 3| extend through the adjusting brackets 26 and 30, and as the shafts are rotated within the adjusting brackets the latter are adapted to be threaded upwardly or downwardly. The adjusting bracket 23 is secured on the inner side of the horizontal channel 25 on the bottom of the window pane 20, and the adjusting bracket 38 is secured to the outer side of the screen frame 23, thereby placing the threaded shafts 21 and 31 in alignment with one another.

The threaded shaft 21, which operates the window pane 20, has a small worm wheel 32 fixedly secured on the lower portion thereof. The threaded shaft 3|, which operates the screen frame 23, has a small worm wheel 33 slidably keyed on the lower portion thereof. This worm wheel 33 is adapted to slide upward or downward on the lower portion of the threaded shaft 3 I, and at the same time, fixed with respect thereto by means of a spline 33A, thus turning the threaded shaft as the small worm wheel 33 rotates. A worm 36 is rotatably supported on a horizontal shaft 3'! which is rotatably mounted to the inner walls. of the pan 38. This worm 33 is driven by an electric motor 39 which is connected thereto by means of the gears 40 and M. A drain 38A provides a moisture outlet for the aforesaid pan 38.

The rotation of the worm 35, which is located between the small worm wheels 32 and 33 and engages both of the same simultaneously, rotates one in an opposite direction to that of the other. As these worm wheels rotate, their corresponding threaded shafts turn in opposite directions, thus either lowering the window pane 20 and raising the screen frame 23, or raising the window pane 20 and lowering the screen frame.

The worm wheel 33, which is slidably fitted on the shaft 3 I, is supported in a suitable horizontal position in alignment withthe worm 35 by means of a shoulder 42 on the shaft. A tension spring 43 is suitably secured to the worm wheel 33 to extend a downward pull thereon, thus tending to seat the worm wheel 33 on the shoulder 32 of the shaft. A disengaging roller 44 is rotatably mounted on the arm 45, and upon upward movement of the latter the roller 45 raises the worm wheel 33 to clear the worm 35. This arm 45 is pivotally secured to one wall of the pan 38 and has a chain 38 secured thereto and extending upward, where the free end thereof is secured to a manual operating pull 47- A small pulley 38 is rotatably supportedby the bracket 49 and the upper portion of the chain A6 rides over this pulley in changing from a vertical to a horizontal position. A plunger 50 forms a connection between the upper end of the chain 46 and the manual operating pull 4?. This plunger is accommodated in a cylindrical member having a slot 52 cut in the wall thereof. A locking pin 53 is fixedly secured in the plunger 50 and projects through the slot 52 in the cylindrical member. A. cut-out portion 54 leading from the slot 52 provides a means of locking the plunger 53 in position when the same is pulled outward and turned sufficiently so that the locking pin 53, extending throughthe. slot 52, enters the cut-out portion 53. In this. manner it will be seen that the worm wheel 33'may'be easily disengaged from the worm 36 by simply raising the arm 45 and chain 43 as the plunger, 50 is manually pulled out by the operating pull 41, thereby permitting.

the mechanical device to operate the window pane 20 only, andleaving the screen frame 23 in a downward position. Whenthe plunger 50 is released and the chain lowered, the arm and disengaging roller, are" lowered thus permitting the tension spring 43 to return the worm wheel 33 to its original position for engagement with the worm 36.

The sill 28 has brackets 55 secured on the upper surface thereof on each side of the window pane 20. These brackets 55 each support a resilient strip 56 which extends inward and upward to rest against the outer and inner surface of the window pane 20. These resilient strips 56 may be of rubber or any other suitable material which will eificiently seal the opening in the sill through which the pane extends, thus protecting the operating mechanism from rain, snow or the like. In the construction of the window, as hereinbefore described, the window pane closes the opening in the wall by being sealed at the sill by means of the resilient strips 56, abutting the top of the window frame 16 and by fitting snugly within the outer channels l8 and [9 which are secured to the sides of the window frame. When the window is in an open position, the screen fills the opening in the wall as the screen frame 23 extends through a suitable sized elongated slot in the sill 28 and the top of the screen frame abuts the top of the window frame 15, while the sides of this frame are-suitably fitted within the inner channels 2| and 22. In this way the window pane 20 substantially closes the opening in the wall when in a closed position and when the same is open, the screen effectively fills the opening to prevent insects and the like from entering the room.
